PERF: Make m_ObjectToWorldTransformInverse->TransformPoint non-virtual

Suppressed the virtual call mechanism for
`m_ObjectToWorldTransformInverse->TransformPoint(point)` by explicit
qualification with the `TransformType` scope, in the five `SpatialObject`
"InWorldSpace" member functions.

A performance improvement of more than 13 % was observed, from more than 0.36
sec. (before this commit) to less than 0.31 sec. (after this commit) when
calling IsInsideInWorldSpace(point) 2^25 times, using VS2022 Release.
